Alyssa finds an amethyst, a stone believed to aid in psychic awareness. Suddenly she's interpreting dreams and making predictions, all with 100 percent accuracy. While half the camp girls are believers, the other half are skeptics, attributing the gem's track record to coincidence. Not that Alyssa cares what anyone thinks. In fact, she's so attached to the amethyst, she names it Amy. But when a prediction causes the bunk to miss a Phillies game—where Justin Timberlake sings—even the believers cross over to the dark side. Still, Alyssa proclaims that the chances of her giving up the amethyst are 'as likely as a snowstorm in July.' And lo and behold, the next morning the campus is carpeted in snow. Coincidence? Only Amy knows for sure . . .
